Register for the freshly-launched and free Expensr, which can import OFX files from your bank for batch transaction entry. Create and manage a list of expense categories (with subcategories, so Food > Restaurants or Food > Groceries) and categorize your transactions as you enter them. Expensr also supports multiple "accounts," though that part gets confusing, as the demo lists "Expenses" and "Income" as two accounts, when you'd expect things like "Checking" and "Savings." Hit the "Category Analysis" tab to see a detailed pie graph of your expenses. Expensr's still very new, but it looks like a promising, stripped-down online alternative to wrestling with Quicken or Microsoft Money on your desktop.
